Inventor: TANAKA AKIO
IPC: B22D13/00
Filed: 1979-06-14
Abstract: PURPOSE:To perform a ferrite-conversion annealing economically by a procedure in which a ductile cast iron pipe made by a centrifugal casting machine is put distributionally into movable heat treatment furnace groups in a red-hot state and then gradually cooled in the transformation point A1 temperature zone or kept at the temperature there. CONSTITUTION:The ductile cast iron pipe 8 made by the centrifugal casting machine 1 is taken out in a red-hot state and then put contributionally and directly into the first to third heat treatment furnaces 14, 15, and 16 of the heat treatment furnace group 12 moving laterally in front of the cast iron pipe take-out port of the machine 1. In each of the heat treatment furnace groups 14, 15, and 16, the cast iron pipe 8 is gradually cooled from 800 deg.C to 650 deg.C while being turned in order to prevent becoming an oval form. Or is kept at 750 deg.C constantly regulated by the burner 21 in a fixed heat treatment furnace. In either case, the cast iron pipe 8 is gradually cooled at the transformation point A1 temperature, so that cementite is decomposed into ferrite and graphite and its texture is sufficiently converted into ferrite. Thus, heat energy used in annealing can be greatly saved because the heat treatment utilizes the heat of the cast iron pipe in a red-hot state immediately after casting.

Title: Inspection of ceramic sinter
Inventor: ABE YUTAKA
IPC: G01N29/04
Filed: 1987-03-31
Abstract: PURPOSE:To accurately inspect a flaw with high accuracy in distinction from noise, by detecting the signal generated when load is applied to set the signal showing a frequency characteristic, which has a peak in the specific frequency region corresponding to the material quality in the generated signal, to an acoustic emission (AE) signal. CONSTITUTION:Load is applied to the center of the ceramic sinter 1 on a jig 2 and the AE signal of a sensor 3 generated at that time is counted. The count signal is amplified to obtain only a signal of a definite threshold value or more by a discriminator 6 and said signal is passed through a counter 7 and an energy detector 8 to record the generation number of signals and generated energy on a recorder 9. After the output signal of a main amplifier 5 is converted to a digital signal by an A/D converter 10 and is subjected to high speed Fourier transform processing by a frequency analyser 11 to obtain a frequency spectrum. This spectrum is analyzed to take up only a signal showing a frequency characteristic having a peak in a frequency region of 50-150kHz as the real AE signal caused by the flaw of the silicon nitride ceramic sinter. In the case of a ceramic sinter composed of other material quality, the real AE signal is obtained in the same way to detect a flaw state.

IPC: B65G65/48
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce a discharge amount and to enhance the accuracy of a stored article discharge amount at the time of transfer between a discharge state and an idle running state by reversely rotating paddle blades each other from a discharge position and folding the paddle blades. SOLUTION: A traveling truck 8 is run along a slit 2, and stored articles 5 are discharged from a storage facility 1 by a delivery wheel 110. When the discharging of the stored articles 5 reaches a prescribed amount, the driving of a first and a second driving devices 71 and 72 are controlled by a control means, a first and a second paddle blades 51 and 61 are reversely rotated each other from a discharge position and then folded (idle running state) so as to be in parallel with the inner position of the slit 2. Thus, if the paddle blades 51 and 61 are reversely rotated each other, compared with the rotation of the paddle blades 51 and 61 in the same direction, the discharge amount of the stored articles 5 necessary for folding is reduced and thus finer control of the discharge amount is performed.

Title: Temperature detecting circuit
Inventor: HIOKI MASAHIRO
IPC: G01K7/01
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To maintain linearity of output voltage, and accurately detect a temperature by connecting an electric current mirror circuit between a reference voltage generating circuit and an output circuit, preventing a change in reference voltage by increasing the input/output side electric current, and simultaneously preventing an increase in input voltage of the output circuit. SOLUTION: Voltage of a nonreversed input terminal of an operation amplifier 3 increases according to a temperature rise, so that output voltage similarly changes. However, when a temperature rises and exceeds a specific temperature in the vicinity where reference voltage starts to drop, on the input side of an electric current mirror circuit, an electric current supplied through a series circuit of resistances R1 , R4 and diodes D1 , D2 is added to an electric current supplied through a resistance R5 . Terminal voltage of a feedback resistance R1 of an operation amplifier 4 constituting a first resistance is increased to thereby prevent a drop in reference voltage. Since an electric current of diodes D3 , D4 connected to the output side also increases, a voltage drop by both diodes becomes large.  Therefore, voltage of the nonreversed input terminal of the operation amplifier 3 is prevented from increasing by separating from a straight line to maintain linearity of output voltage to a temperature change so as to accurately detect a temperature.
